Goal with Master thesis
Looking at the datasheets, Gallium Nitride (GaN) MOSFETs has overtaken silicon (Si) MOSFETs as the better alternative for switching devices for DCDC converters. Whether it is high frequency capability or low conduction losses, GaN MOSFETs has the edge when comparing similar package sizes. However, the datasheet doesn’t tell the whole story. This Master Thesis shall compare an existing Ericsson developed Si MOSFET based DCDC converter with a GaN based DCDC converter. The GaN based DCDC converter shall be developed in this Master Thesis.
Master Thesis in short
Literature study, with GaN and its drawbacks in focus.
Develop a GaN MOSFET based DCDC converter with a potential to replace an Ericsson developed Si based converter.
Perform comparative tests on GaN and Si converters.
Perform robustness and quality tests
Theoretical analysis, literature study, design and evaluation of hardware
Education: Masters within Electrical engineering, Physics engineering or similar
Basic knowledge of Switched Mode power supplies and semiconductor devices
English language skills (fluent both in written and verbal communication)
Suitable for 1 or 2 students
